A/N: Hi, everyone! Thank you so much for reviewing :) I'm slowly catching up on reviewing everyone else's fics, but my inbox says I still have 82 left to go so sorry if I haven't gotten to yours yet. (This is what I get for taking such a long break...facepalm) Anyway, enjoy!

Disclaimer: If I owned them, we wouldn't be having to put up with the BTTS crap

Bishop pushed Stockman away as alarms began to blaze again. The robot body spun around several times before collapsing in a heap. Bishop ran to the NARF's control panel, growling as Donatello's vital measurements showed to be dancing all over the place.

"Damn it, Stockman!"

He pushed a button, bringing a keyboard out of a slot. Typing furiously, several tubes snaked their way towards the unconscious turtle. Glancing up for a moment, Bishop's eyes widened.

Donatello's eyes had opened; they were glowing red.

The turtle's body began to convulse as muscles bulged in ways that they should not. Something seemed to be crawling quickly, desperately, through the green body.

"What the hell?" Stockman picked himself up off the floor.

"Doctor, get the outbreak antidote and do it quickly."

"But—"

"NOW, Stockman!"

The android spun around, tripping over his own legs, and hurried out of the room. As Donatello's body grew larger, Bishop pulled out a comlink. "Touch, Go, get to the lab immediately."

Donatello let out a terrifying guttural cry, making Bishop unconsciously step backwards. The mutating turtle's arms and legs strained against the NARF's influence. Yet another warning alarm began to sound as Donatello began to move. Suddenly, as though ropes had snapped off of him, the turtle hurtled forwards, slamming into the yellow barrier. The entire device shook violently.

Mr. Touch and Mr. Go rushed into the room just as Donatello's claws raked against the barrier with an ear-piercing screech. All three men winced and covered their ears.

The turtle began to hurl himself at the long scratches. Cracks burst out from the marks with every hit.

"Restraining and sedating him is our top priority. We must absolutely not allow him to escape!"

"Understood." Mr. Touch slammed his fists together, causing them to glow. Mr. Go spun his cane around.

For a brief, tense moment, no one moved. Then, with a mighty crash, Donatello broke through the barrier and leapt out into the room.

The summer's humidity had finally given way to a full-fledged thunderstorm. Lightning snaked across the sky, briefly showing the three figures dashing across the rooftops. Most sane individuals had taken refuge inside and those that had not darted from overhang to overhang, tightly clutching jackets and umbrellas.

"Come on, Case. Keep up."

"Well excuuuuse me for bein' waterlogged. I've gotta wear clothes, 'member?"

"Just come on."

Casey's eyes opened wide under his hockey mask. He had never heard Michelangelo so serious ever before. "Look, we'll find them. It'll be okay."

"But what if it isn't?" Michelangelo skidded to a halt. "What if something really awful happened to them?" He waved his hands frantically.

"Nuthin's gonna happen." Raphael walked back to the others and put his hand on his brother's shoulder. His eyes flashed grimly, reflecting the lightning above. "I don't care if we've gotta search this entire damned city, we're gonna find 'em and bring 'em back with us."

"But what if it's like last time, when the Shredder found Leo, and…and…" His voice hitched.

"That's why we're out lookin', goofball." Raphael squeezed his brother's shoulder, then turned away. "Now come on, we've got more ground to cover."

Biting his lower lip, the youngest turtle wiped what he pretended to be rain away from his eye and started running across the rooftop's wet gravel, closely followed by his brother and Casey.

Several rooftops later, Michelangelo slowed again. "Look, it's the water tower that Master Splinter used to always tell us to meet at if we got lost out here when we were little."

"Thank god," a voice said softly under the tower, almost lost in the rain. A lumpy shadow detached itself from behind one of the posts.

"Leo?" All three searchers rushed forwards.

"LEO, LEO, LEO!" A huge smile bounded across Michelangelo's face but it was soon replaced with concern as soon as he could clearly see his brothers.

Leonardo smiled slightly, relieved, as he dragged Donatello's limp form with him. Both were sporting fresh bruises and Leonardo's bandages were sopping. "Don's hurt, but I don't know what's wrong."

Raphael took the clone's body as Leonardo struggled under the weight. "What the shell happened to you?"

"Bishop, but I'll tell you more later." Leonardo's exhaustion was evident.

"Hey, my place is real close ta here. Why don't we go there?" Casey suggested.

"Sounds good," Raphael agreed. "Then we can call Sensei an' April an' have 'em look these two over." He glanced worriedly down at the unconscious body in his arms. "An' hopefully Don'll wake up."

Donatello swung wildly at the three men. Bishop and Mr. Go leapt out of the way, but Mr. Touch braced himself, taking the full brunt of the turtle's heavily muscled arm directly in his stomach. Grunting, he skidded backwards slightly while grabbing onto Donatello's arm.

The mutant roared.

Straining his arm, Donatello pushed Mr. Touch farther backwards. Mr. Go leapt up onto the turtle's back and swung his cane around Donatello's neck. He pulled back with all his might.

"Surrender now, or my dear Mr. Touch and I will be forced to injure you severely."

"Nooooo." Donatello's voice was gravelly, strained. Yet it startled all three men.

"So, you have retained some of your consciousness." Bishop moved slightly closer. "I was certainly right that you are a fascinating test subject."

Donatello suddenly let out an enormous smirk, showing several of his now-pointed teeth. He reached back and grabbed Mr. Go by the head.

The man screamed as the grip on his head tightened, squeezing mercilessly. The moment that the cane loosened from around his neck, Donatello yanked Mr. Go off of his back and swung him around like a whip into his partner. Unable to keep his grip on the turtle's arm, Mr. Touch flew backwards, crashing into the computer consol. Sparks flew. Milliseconds later, Mr. Go landed on top of him.

Donatello spun around to face Bishop. The man cracked his knuckles.

The turtle roared again.

Just then, the lab door opened as Stockman came back in, cradling several dart guns. Without missing a beat, Donatello charged towards the opening.

"SHUT THE DOOR!"

Instead of following Bishop's orders, Stockman took a shocked step backwards, allowing Donatello to race past him, pushing him over like a scarecrow.

"Useless moron!" Bishop rushed past the scientist, grabbing one of the guns that had scattered into the hallway. He paused for a brief moment, slamming his fist though a glass case and into a red button. Alarms blared throughout the building. As he dashed down the hallway, Touch and Go followed closely behind.

"It seems our prey has become much more interesting, don't you agree my dear Mr. Go?"

"Indeed, Mr. Touch." The smaller man wiped away a trickle of blood from his brow.

"And it is going to get even more interesting, gentlemen. We cannot allow him to get out." Bishop raised the dart gun and fired.

The dart embedded itself in Donatello's shoulder. He stumbled slightly but did not stop fleeing. Skidding around a corner, the mutant disappeared from the men's view. Seconds later, the pursuers reached the same corner.

The hallway stretched before them with several other halls branching out from it. Several soldiers were pouring in towards them, none seeming to have met up with the escaping turtle.

Donatello had disappeared.

"Damn it…"

"Sir!" A sergeant saluted. "What are your orders, sir?"

"We have a code fourteen-ninety. Subject would be best captured alive but lethal force is authorized if necessary."

"Sir, yes sir!" The soldier hurried away.

Bishop turned to the assassins. "Gentlemen, your orders are the same. Do not disappoint me."
